Move Zeroes

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

Example:

Input: [0,1,0,3,12]
Output: [1,3,12,0,0]

Note:

1. You must do this in-place without making a copy of the array.

2. Minimize the total number of operations.

class Solution {
    public void moveZeroes(int[] nums) {
        int pointer=0;
        int pointerZero=0;
        while(pointer<nums.length){
            if(nums[pointer]!=0){
                if(nums[pointer]!=nums[pointerZero])
                {
                    int temp=nums[pointer];
                    nums[pointer]=0;
                    nums[pointerZero]=temp;
                }
                pointerZero++;
            }
            pointer++;
        }
    }
}
